WEED AND ROOT PULLER.

SPECIFICATION forming part of Letters Patent No. 473,890, dated April 26, 1892. Application filed September 12, 1891- Serial No. 405.508- (No model.)

IVHEELOCK, the body 1 its connection through the ina citizen of the United States, residing at Determediation of the arms 7 with said jaws corah,in the county of WVinneshiek and State will cause their lower ends to be brought 5 5 5 of Iowa, have invented certain new and usefirmly together, while an opposite movement ful Improvements in WVeed and Root Pullers; of said sleeve will draw the cutting-blades of and I do hereby declare the following to be a the jaws apart. full, clear, and exact description of the inven- In order to more effectively control the tion, such as will enable others skilled in the locking feature of the jaws, I provide the 10' art to which it appertains to make and use the bracket 10, which consists of a U-shaped loop same. of sheet material, each end of which is se- My invention relates to improvements in cured to one of the arms 7 immediately on the weed and root pulling implements; and itconinner side of the aperture 8 therein.

The auxilhandle provided with two clamping jaws iary clamp-arms are affixed to one side of one 25 adapted to take into the soil underneath the of the guides 2 by means of the anchor-plate root and either clip the same or draw it out 13, which lies parallel with said guides and of the ground, as will be hereinafter fully set has its ends affixed thereto. forth. Having thus described the construction of Referring to the several parts by their remyimproved weed and root pulling machine, 3o speotive figures of designation, 1 is the body it is operated as follows: In order to open the proper, consisting of a cylindrical or other jaws, Ihe sliding sleeve 6 is forced downward form of rod, to the lower end of which,at right upon the body, carrying with it the laterallyangles thereto, is secured the guide 2, said reaching arms 7.Which, being in engagement guide being rigidly secured at the lower end with the open ends of the clamping-jaws, fol- 35 of said body. The guide 2 consists of two low the curved body thereof downward, and sections 2 arranged parallelwith each other, thus throw the cutting-blades away from each between which are pivotally secured at either other or open the machine ready for being side of the body the incisor-jaws 3, having at inserted into the earth.

In order to control the operaweed or root to be extracted, when the foot tion of said jaws, I mount upon the body 1 the of the operator may be placed upon one of sliding sleeve 6. Said sleeve carries at its the extended ends of the guides 2, causing lower end the arms 7, the outer ends of each the cutting-blades to take into the soil on 45 being provided with apertures 8, adapted to either side of the root, when the sleeve, by

The the same outward and simultaneously draw- I00 50 upper ends of the jaws 3 are curved slightly ing the cutting-blades toward and against inward toward the body, and it will be seen each other. A corresponding effect is produced upon the auxiliary clamp-arms 11- that is to say, when the sleeve is drawn upward the loop 10, encircling the upper portion of said arms, draws the same toward each other and at the same time causes the lower ends of said auxiliary arms to bear firmly against the lower ends of the clamping-jaws 3, thus bringing pressure to bear directly above the cutting-blades or at that point most needed to effectively hold the jaws together in their operative position.

The construction just described results practically in providing a locking device for the jaws when the same are brought into engagement with the root, rendering it impossible for the root to slip between the cuttingblades until the sleeve is again forced downward.

Believing that the advantages, operation, and construction of my improved root and weed pulling implement will be made clear from the foregoing description, considered in connection with the accompanying drawings, further reference thereto is dispensed with.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a root and weed pulling implement,

substantially as described, the combination, with the body, the parallel guides secured thereto, the blade-carrying jaws 3, pivoted between the guides, and the auxiliary clamparms pivoted to the guides and having their lower ends bent to engage the blade-carrying jaws, of the reciprocating sleeve mounted on the body, the transverse arms 7, fixed to the lower end of said sleeve and engaging the upper portion of the blade-carrying jaws, and the loop 10, connected to the transverse arms 7 and engaging the upper portion of the auxiliary clamp-arms, substantially as specified.

2. In a root and weed pulling implement, the combination of the body, the parallel guides secured thereto, the reciprocating sleeve mounted upon said body, the bladecarrying jaws 3, pivoted between the guides, and the transverse arms 7, affixed at the lower end of the sleeve and adapted to control the blade-carryin g jaws, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
